Used primarily in analytical chemistry as a reference material for calibrating instruments and verifying the accuracy of measurements in various testing procedures. It is essential in atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) techniques to ensure precise quantification of magnesium in samples. Additionally, it serves as a critical component in quality control processes across industries such as environmental testing, pharmaceuticals, and food safety, where accurate magnesium detection is vital. It also aids in research and development for studying magnesium's role in biological systems and industrial applications.
